Mechanical password door lock structure

The invention relates to a mechanical password door lock structure, in particular to a door lock structure which can be applied to a tubular door lock [commonly known as a horn lock].

Locks have always been an indispensable anti-theft tool in daily life, and their application has become quite common. Whether it is getting up in the morning and going to bed at night, it will continue to contact and respond, such as toilet doors, personal doors, house doors, Office entrances, lockers, safes, transportation, etc. are all equipped with locks.

Among them, the most frequently contacted is the door lock of the entrance and exit. Generally, the locks commonly used in the entrance door are mostly cylindrical door locks (commonly known as the horn lock), and the key corresponding to the lock must be unlocked, so the user must carry it. Carrying the key to avoid the embarrassing situation that is locked outside the door and unable to enter; because the size of the general key is not large, it is easy for the user to ignore and forget or forget to carry it, and if the user needs to enter and exit multiple buildings, It is necessary to carry a plurality of keys. As a result, the volume and weight of the key are doubled, and problems such as inconvenience of carrying are easily caused, so that the use is still inconvenient.

Therefore, some operators have developed an electronic key lock, which allows people to unlock the door by entering a password without using a key. However, such a door lock usually requires a power supply device [such as a battery or powered by a socket]. In the event of a battery exhaustion or insufficient power, it is easy to cause the electronic door lock to fail and not function properly, so that users are not allowed to enter the door, and it is also possible for the thief to take advantage of it and cause the user to Financial loss; secondly, common buttons Most of them are only for the ten digits to let the user do the password combination. This kind of variability is too small, so there is still a safe place to use.

Among them, through the application of the password lock group (E), 36 word parts (E311), false As shown in Fig. 6, when four sets of ring groups (E3) are implemented, the combined password strings can be arranged, and there are 1,679,616 changes [36X36X36X36=1679616] can be selected, and 36 word parts ( E311) Its superior application choice is composed of 26 English letters and 10 Arabic numerals for users to use flexibly, avoiding all digital or English letters to be implemented, so as to prevent being easily cracked by the minded person. Extend the decoding time. Of course, the word part (E311) can also be implemented in the following ways, consisting of 26 English letters and 10 punctuation marks, 26 punctuation marks and 10 Arabic numerals, and 26 different national phonetic symbols. And the composition of 10 Arabic numerals, but in order to make the same consensus among the people of the world, 26 English letters and 10 Arabic numerals that can be understood by people all over the world are the best composition examples; 36 codes Department (E311), in use, has a very high security, in the combination of passwords, it will be more complicated than traditional password locks. Nowadays, all mechanical password locks in the world do not have this application.

Secondly, the pusher (C) is an internal part, and the second part cannot be destroyed by the outside, so High security.

In addition, the setting of the door wrench (H) can be opened only by light pressure. The door can be opened, and its structure is special with a spring (D) against the front bend, and the door wrench (H) cannot be pulled out under normal conditions.

In addition, the application of the variable code protection board (1) protects the blocking code rotation button (E1) Destroyed by violent rotation, and in the state of locking the door [that is, when the password outside the door is incorrect], it is even more difficult to pull Move, move or disassemble the variable code protection board (I) and the door opener (H) for high safety.

In the above, the inner and outer connecting device (7) further includes a An inner baffle (71) at one side of the door handle (1); an inner and outer connecting seat (72) disposed at a side adjacent to the outer door handle (G); one of the inner and outer connecting seats (72) a locking tongue control seat (73) connected to the locking tongue (300); one of the inner and outer connecting seats (72), one end protruding toward a side adjacent to the outer door handle (G), and An outer connecting tube (74) connected to the inner code fixing seat (E2); an outer baffle disposed between the inner and outer connecting seat (72) and between the locking tongue controlling seat (73) and the outer connecting tube (74) ( 75); at least one is disposed in the bolt control seat (73), parallel to the bolt (300), and one end abuts against the inner and outer joints (72) of the strong compression spring (76); a central section from the The inner and outer joints (72) and the tongue control seat (73), adjacent one end of the bolt (300), perpendicularly to one side of the bolt (300), pass through to the other side, and have a U-shape, which can be matched The door inner locking button (3), the steel wire (77) for allowing the locking tongue (300) to enter the locking state; and one of the inner and outer connecting seats (72) away from the end of the locking tongue (300) In addition, the two ends are respectively connected with the corresponding ends of the steel wire (77), and the steel wire (77) can be used for positioning. Positioning spring (78).

Whether it is impacted or knocked, the steel wire (77) will not bounce, resulting in the door lock. The opened condition occurs and the safety is high. However, the most commonly used tubular door lock [commonly known as the horn lock] has this safety problem.

Secondly, the tubular door lock [commonly known as the horn lock] is a kind of door lock with a structure. To the structure of the traditional key lock, you must consider the force of turning the key, press the spring to unlock, so the pressure spring can not be too gravity, such as the pressure of the compression spring is too large, it will cause the key to twist and deform when the key is turned, the spring pressure is too light There will be a door opening card, no key, it can be used to shock the safety concerns, so the opening and closing structure of the present invention is different from the cylindrical door lock [commonly known as the horn lock], the pressure of the strong compression spring (76) can be larger It makes the door lock more durable and has no safety concerns.

Moreover, since the present invention does not use a key, the pressure of the strong compression spring (76) can be compared. Big, no big, there will be no concern that the traditional key will be broken.

In addition, the outer connecting tube (74) can be used to connect the outer side of the extension door (200).
